An unidentified man was detained by Taylor Swift 's security after showing up at her New York apartment on Tuesday night.

The man - described as "disorientated" by law enforcement services - was handcuffed by security at Swift's Tribeca home at around 6pm before calling 911, TMZ reports, but so far hasn't been booked for any crime.

Police were seen searching the duffel bag he had with him, while he stood by handcuffed and according to sources appeared "emotionally disturbed".

He was taken away in an ambulance for hospital evaluation.

The 1989 hitmaker - who bought the sprawling Tribeca home in 2014 - wasn't at home at the time according to the report and it's unclear if he made any threats or gained access to her home.

The singer was safely across the country while the drama was going down at her New York home, picking up a string of awards at the 64th annual BMI Pop Awards held at the Beverly Wilshire Hotel in Beverly Hills, California.

The singer managed to make history at the awards show - no change there then - winning Pop Songwriter of the Year and the very first Taylor Swift award.

It's only the second time an honour named after an artist has been handed out, the first being for Michael Jackson in 1990.

It was given to the singer in recognition of her creative and artistic talent and influence.
